Thread and yarn clearer



Aug. 15, 1933. s. HY SLOP THREAD AND YARN CLEARER Filed Feb. 1, 1932Patented Aug. 15, 1933 UNITED "STATES PATENT OFFICE 4 Claims.

This invention relates to thread and yarn clearers for use in connectionwith winding machines and the like for the purpose of clearing thethread or yarn of objectionable slubs, knots, bunches, etc, as it iswound upon the bobbin.

This invention is an improvement upon the mechanism of like natureprotected by my previously issued patents numbered respectively1,740,242 and 1,499,929.

9 an edge elevation of the element shown in Fig. 8.

Referring first to Figs. 1, 2 and 3 of the drawing, my novel andimproved thread clearer is shown as comprising a base 1, in this caserectangular, preferably of metal. This base has, at a suitable pointthereon, (Fig. 2) a hook-like member 2, adapted to embrace the usuallifting rod 3, broken away, of a winding machine, not shown, althoughany convenient locking member may be used to lock it to any suitablemember of the machine.

The inner threaded end of the member 2, Figs. 1, 2, is extended throughthe base 1, and provided with a nut 4 for locking the base to the member2, and the latter to the rod 3.

The base, Fig. 1, is preferably provided with a suitable number, hereintwo, of thread guides 5, to direct the thread to and from the clearingelements. The thread clearing elements in this improved construction,Figs. 1, 2, 6 and 7, comprise broadly a plurality, herein two, ofcurvilinear members, one (Fig. '7) a ring 6 with two upstandinghorizontally curved posts 8, 8, slotted vertically at 9, and a neck 10by means of which it is, to a limited extent, swingably mounted, Figs.1, 3, 5, on a stud 11 on the base 1. The other clearing member is shown,Figs. 1, 4,, 5, 6, as

a collar 12 slotted vertically at diametrically opposite points 3, andprovided also with a neck 14 by means of which it is swingably mountedupon the stud 15, Figs. 1, 5, 6, dotted lines, the slots 13 in themember 12 normally registering with the slots 9 in the member 8. Themember 12 is retained in its position on the stud 15 by a locking member 16 pivoted in the base and mounted to turn thereon to overhang thearm 14 of the member 12.

The member 12 overhangs the member 6 and owing to the fact that theapertures in the arms 10, 14 are slightly oblong perpendicularly of thedevice said members have limited relative rotary motion one within theother and about their pivots 11, 15, and the slots 9 and 13 are usuallymade of a size to take the maximum size thread it is desired to use on agivenpiece of work. Downward movement of the member 6, Fig. 3, isprevented beyond the normal position by a pin 66 depending from the edgeof member 6 in a slot 67 in the edge of the base.

To permit the ready use of a thread of different size, however, withoutdelay, and the services of a skilled mechanic, I have conceived andprovided a novel thread-slot-reducing means in the form of a collar 17,Figs. 8, 9, with slots 133 like the slots 13 of the collar 12, Fig. 6,but ,of reduced size, which collar is slipped over and about the collar12, Fig. 5, a cutaway portion 18 of the lower edge of the collar, Fig.9, causing it to seat on the arm 14 of the collar 12 and the slots 13 inthe collar 1'7, see Fig. 5, to register with those in the member 12 andthus to reduce effectively the size of the thread that may passtherethrough. I

The thread clearer is usually positioned on the machine at about theangle shown in Fig. 2, so that the members 6, 12, normally act to returnto normal position through gravity.

The thread 19 normally runs freely through the slots 13 in the member 12and the slots 9 in the member 6, see Fig. 1, but, should a slub, knot orsnarl or any objectionable imperfection greater than the slot 13 or slot9 approach either slot, the snarl will not pass through the slot butwill be stopped thereby, and cause the member 12 to swing about itspivot 15 and the ring 6 to swing about its pivot 11, throwingthe slots13 and 9 out of register, and the pull of the machine will break thethread and either automatically stop the machine, by means for thatpurpose but not shown, or attract the attention of the operative, whowill give the situation the required attention, after which the members12 and 6 will automatically swing back to normal position.

If it is desired to reduce the size of thread to be used in the machine,one need only to select the collar 1'7 with slots of the required size,slip it over the collar 12 and the machine is instantly adapted for thedesired change. The slot reducing collars are usually made with slotsprogressively larger by about two-thousandths of an inch in width, andas many may be provided as are desired. Thus the change in the threadclearer size may be made instantly and without the services of a skilledmechanic and as frequently as desired without delay.

Devices for this purpose are constantly gathering lint, oil and dust andfrequently need to be cleaned. Practically all wool, and much of thecotton and silk used for yarn or thread and wound upon machines on whichmy clearer is used, has a substantial amount of oil and other materialsworked into it in'the finishing of the yarn to allow it to be handledconveniently in spinning and winding under unfavorable atmospheric andother conditions.

Lint and dust are also present in large quantities and combine with theoil to make trouble; When the slotted thread receiving members areconstructed like the members 7 and 9 shown in my former Patent #l,l99,929, or like the members 10 and 12 in my Patent #1,".40,242 which,in both instances, fit closely and with no clearance, one within theother, the lint, dust and oil combine on top of and around said membersand sometimes interfere with the satisfactory operation of them.

To overcome this difiiculty, I have designed the present improvedconstruction. The posts 8 instead of fitting close to the collar 12 arebuilt on a shorter radius and providing a triangular dust receivingchamber 88 between thenr'and the adjacent'collar 12 which permits theoily lint and dust to fall away from the adjacent faces of the posts 8and collar 12 and thus avoid a large part of the difficulty abovereferred to.

' However, my novel clearer is very easily cleaned.

I collected lint, etc., or for the yarn to delint itself While passingfrom one post to the other and by turning the locking member 16 to theleft, Fig. 5, dotted lines, the collar 12 may be lifted from post 15 andthe ring 6 and the latter lifted from g the post 11 and more thoroughlycleaned if desired. Furthermore, the shape and relation of the twothread clearing members herein so reduces the extent of the frictionsurfaces as compared with my earlier constructions that it ispractically negligible and plenty of clearance is provided to reduce thelint and dust collecting features to a minimum.

My device is very simple and inexpensive to construct, easy to maintainand effective in operation.

My invention is not limited to the particular embodiment thereof hereinillustrated and described.

I claim:

1. A thread clearer comprising a base, a ring and a collar thereon withregistering thread slots providing normally a straight thread path, saidmembers overlapping and eccentrically mounted for swinging movement toprovide a tortuous thread path when moved by an imperfect thread, and aswinging locking member on the base to removably secure the collar andring thereto.

2. A thread clearer comprising a base, means to lockit to a machine, aclearing collar and a clearing ring, the latter with upright postswithin the collar, and providing therewith wedge shaped lint receivingand removing chambers, the collar and posts having radially registeringthread slots, and swingable out of registering relation when either imoved by an imperfect thread.

3. A thread clearer comprising a base, means to lock it to a machine, aclearing collar, and a clearing ring with upright posts within thecollar, the posts curved in outline and of a radius less than andcircumferentially non-concentric with the collar, the collar and postshaving radially registering thread slots, and swingable out ofregistering relation. when either is moved by an imperfect thread.

i. A thread clearer comprising a base, a clearing collar, and a clearingring with upright posts within the collar, the posts curved in outlineand of a radius less than and cirnnferentially nonconcentric with thecollar. the collar and posts having radially registering thread slots,and swingable out of registering relation when either is moved by animperfect thread, and a second thread slot changing collar with narrowerthread slots therein registering with the slots in the first namedcollar and adapted to fit snugly over the said collar to determine thesize of the thread to be passed therethrough.
